  • Page 16: Inputs

    Inputs There are four types of inputs to the BE1-79A relay. They are: • Operating AC/DC Power • Contact Sensing Inputs • Reset Switch • Serial Communication Port Operating AC/DC Power. Operating power for the internal circuitry is applied to the isolated internal switching power supply.

  • Page 17: Microprocessor

    This serial port provides the means to configure and read relay settings. Microprocessor All reclosing and communication functions are coordinated by the microprocessor. The BE1-79A uses an eight bit microprocessor with integral ROM (read only memory) and RAM (random access memory).
  • Page 18 The BE1-79A has ten outputs. The function of each output depends on the operating configuration of the relay. Tables 3-3 and 3-4 provide a description of each output for each relay configuration. Table 3-3. Outputs Description for ACR11A Operation Output...

    > is returned for a valid command, ? is returned for an invalid command. Commands received by the BE1-79A consist of two types: requests for information and changes to operating parameters. Commands to change parameters are identified by an equal sign (=). The operating parameters to the right of the equal sign are intended to replace the current operating parameters related to the command.

  • Page 37: Motor Input Voltage

    No adjustment is required for the motor voltage applied at terminals 5 and 6. The applied voltage can range from 120 to 240 Vac or 125 to 250 Vdc. These terminals serve as the input to the BE1-79A power supply and control functions.

  • Page 38: Timing Cams

    18 cycles for transmission voltages (including breaker operating time). The inherent delay of the BE1-79A relay is 22 to 48 milliseconds when set at a time delay of zero. The reclose timers may be adjusted in increments of 0.1 seconds which is 6 cycles on a 60 Hertz system.

  • Page 39: Communication Connections And Settings

    The relay settings are fixed at 9600,8N1 where 9600 = baud rate, 8 = number of data bits, N = no parity, and 1 = 1 stop bit. Since the communication settings of the BE1-79A are fixed, you must adjust your communication program settings to match the relay settings.
